How to Draw Cars

Posts Tagged ‘worst case’

I know that stock cars typically run anywhere between 80-90 amp alternators, but I was curious of how much of that is actually under constant load? Say worst case senario, driving with the high beams on radio blaring, wipers wiping, honking the horn etc. I’m trying to find out if the average American vehicle can handle and additional 30 amps of constant load without over straining the alternator. If not that much what would the limit be? Thanks for any help.
